Definitions

  • the invention relates generally to depositcontrol fuel additives which are free from halogen, and more particularly to hydroxypolyalkene amines, such as hydroxypolybutene amines and hydroxypolypropylene amines, as well as to a generally multiple-step process for their production.
  • Deposit-control fuel additives effectively control deposits in engine intake systems (carburetors, valves, fuel injectors, etc.).
  • a major deposit-control fuel additive used in gasoline today is made by the chlorination of polybutene to produce an intermediate followed by the reaction of this intermediate with an amine compound to produce a polybutene amine.
  • These polybutene amines typically contain from about 0.5 to about 1.0 percent residual chlorine, and seldom less than 0.25 percent chlorine. With today's concerns regarding halogen compounds, it is desirable to reduce or eliminate chlorine from fuel additives.
  • the present invention relates to halogen-free hydroxypolyalkene amine fuel additives.
  • This fuel additive is produced through the epoxidation of a polyalkene followed by the reaction of the epoxypolyalkene with an amine to produce a hydroxypolyalkene amine.
  • U.S. Patent No. 4,302,215 to Lewis relates to hydrocarbyl carbonates and their fuel compositions which are deposit-control additives in gasoline compositions.
  • U.S. Patent No. 3,794,586 to Kimura et al. relates to a lubricating oil composition containing a hydroxyalkyl-substituted polyolefin prepared by reacting a polyalkene epoxide with a polyamine at a temperature of from 15 to 180°C.
  • Blackborrow et al. relates to a process for producing long chain alkyl amines from polyolefins by reacting (a) a polyolefin having a molecular weight in the range of 330-2000 with ozone in the presence of a solvent, (b) reacting the ozonolysis product from (a) without separation and/or isolation of the carbonyl compounds formed therein with a primary hydrocarbyl amines to form an imine, (c) hydrogenating the imine from step (b) to give an amine in the presence of a hydrogenation catalyst, and (d) recovering the long chain alkyl amine from the hydrogenation products formed in step (c).
  • European Patent Application No. 385,039 to Blackborrow relates to a process for producing active carbonyl compounds predominating in aldehyde groups from polybutene having at least 50 percent of the unsaturation in the terminal position.
  • the process has an initial epoxidation of the polybutene followed by isomerization of the epoxide so formed at a relatively higher temperature.
  • the active nature of the carbonyl group enables these compounds to be converted to the corresponding amines or imines which can be used as fuel and lube oil additives.
  • the present invention relates to halogen-free hydroxypolyalkene amines such as hydroxypolybutene amines and hydroxypolypropylene amines and to a process for their production, and to a fuel containing such amines as a fuel additive.
  • the structure of the hydroxypolyalkene amines is generally a function of the end group structure of the polyalkene and generally several such structures exist for each polyalkene compound.
  • the following are examples of some of the end group structures in polybutene and the hydroxypolybutene amines generally derived therefrom.
  • Cationically polymerized polypropylene suitable for use in this invention contains several different end-group structures resulting from extensive rearrangement during manufacturing. These end-group structures are represented as 3 or 4 carbon atom-terminated polypropylenes in the preceding structures. When 4 carbon atom-terminated structures are involved, such is due to alkyl group migration from one of the preceding repeat units.
  • n 3 or 4
  • Polyalkene is polypropylene or polybutene, and where, as apparent from the above formulations, the hydroxyl group and the amine group are always attached to adjacent, i.e., an adjoining or contiguous carbon atom.
  • the hydroxypolyalkene amines of the present invention are produced by a multiple-step process in which a polyalkene is first epoxidized in a suitable solvent using hydrogen peroxide in the presence of an organic acid.
  • the intermediate epoxide is subsequently treated with a primary or secondary amine compound which may be a monoamine, a diamine, or a polyamine causing addition of the amine compound to the polyalkene epoxide intermediate.
  • This addition reaction is run either neat or in a suitable solvent with an excess of amine at a temperature of from about 185°C to about 300°C.
  • a process for making a halogen-free hydroxypolyalkene amine product generally of the formula
  • n 3 or 4
  • Polyalkene is cationically polymerized polypropylene or polybutene
  • the hydroxyl group and the amine group are attached to adjacent carbon atoms. That is, the amine group is attached to one carbon atom which is connected to the next or contiguous carbon atom which has the hydroxyl group thereon. Due to the large number of possible isomers, a single generic formula with amine on one carbon atom and the hydroxyl group on the next carbon atom cannot be drawn, rather specific examples have been set forth hereinabove and below.

  • a polyalkene is epoxidized.
  • the polyalkene can be any polyalkene known to the art and to the literature with the initial alkene monomer containing 3 or 4 carbon atoms, with 4 carbon atoms being highly preferred.

  • the end product has the general formula
  • Polypropylene is the commercial name for polymers manufactured from C 3 olefin refinery streams of catalytic or steam-cracked petroleum. In the manufacture of polypropylene utilizing cationic polymerization, there is opportunity for carbon atom rearrangement. Thus, a generic formula cannot be set forth inasmuch as the polypropylene end group structure will contain one unsaturated point within the three or four terminal carbon atoms as set forth above in the various formulas.
